selfish..maybe

I believe everyone has a tendency to be selfish but I just came across some news in my life that renders me speechless.
i just get tears streaming down my cheeks at random occasions.
driving
reading
talking
bathing
running
breathing
sleeping
maybe just two tears or one with a quick swift movement of being whipped away.
no evidence left behind
because if he isn't crying about it why am I?
It all seems so selfish... no
He : is my Father
My hero
The man who gave me these hazel eyes and dirty blond hair, this perfect tan and althethic build
who will in the next three years no longer be able to walk
who has beat cancer, fought for his life, jumped out of planes for the air force,
who has had over 28 surgeries who will soon slowly lose his ability to walk.
my father
my dad
mine.
his spine will deteroriate.
it will happen
is it so selfish to want him to chase my son around the bases, to walk me down the aisle but isn't it the same as strolling,
is it selfish to want to run one more lap with on the track
to no longer see him wake up with his body distorted
is it so selfish
to just ask God to let me take his pain
when he asked God to do the same for us
nothing has happened to me ever.................
fractured my finger
that is it.
is he really taking my pain and absorbing into his only human life form
can't I ask for the same
i will take it
just so he can walk
give me something
is it selfish?
maybe.
